MySensors - Gateway to Domoticz

[joshmosh]

Robbert,
thank for your help. But my understanding of the whole story is somewhat different. Perhaps one of the implementors of the gateway can chime in

Under another topic in this board I found the following comment:

Re: Supported sensors
by AWI » Thursday 26 March 2015 14:15

To answer you question: look at the beta code below (http://sourceforge.net/p/domoticz/code/ ... rsBase.cpp)
These are currently supported types for the "SET" function (Domoticz reads these sensors one way or another).

The "REQ" function is (and will be.. http://www.domoticz.com/forum/viewtopic ... =80#p37901 ) only supported for the V_LIGHT, V_DIMMER and V_VAR types.

So this says that there is a REQ funtion, although restricted to a few types, which is fine with me.

Hi Josh,

I think you can send REQ to other Mysensors devices, not directly to domoticz. I think it is possible to do a request to the gateway and the gateway makes a request to domoticz, but you need to implement this yourself.
If you look in the Mysensors API youll find this at the requesting data tab:

Requests a variable value from gateway or some other sensor in the radio network. Make sure to add callback-method in begin-method to handle request responses. If you send this request to some other sensor-node you must handle the reply message yourself in the destination node.

Code: Select all

void request(uint8_t childSensorId, uint8_t variableType, uint8_t destination);

childSensorId - The unique child id for the different sensors connected to this Arduino. 0-254.
variableType - The variableType to fetch.
destination - The nodeId of other node to request data from in radio network. Default is gateway.

So you need to handle the request yourself.
I hope this helps you.

Robbert

From the quote above I deduct that you can send REQUEST messages to the controller (Domoticz). Domoticz only deals with a subset of types of variables - fine, no problem for me.
Your excerpt from the MySensors API says under destination: Default is gateway. My understanding is that the gateway passes it on to the controller, same as for example with SET messages. I am logging the serial interface to Domoticz and I can clearly see that a REQ is sent to the controller: 21;3;2;0;2 (21 is my node id, 3 is child id, 2 is REQ, 0 for no ack requested and 2 is variable type V_LIGHT)

Somewhere else on this board there is an example how to request variables from Domoticz, but since V_LIGHT is supported, there is obviously something that I am doing wrong.

So, Robbert, no offence and again thank you for your help. Perhaps somebody can direct me to my misunderstanding.

Cheers
Josh

I would say paste your serial monitor output from the node and a link to the sketch. The default relay sketch RelayActuator.ino handles incomming on/off messages from the controller and it should treat a response to the node request in the same maner. The serial monitor should tell you if Domoticz is responding to your requests.

Good idea. In fact, I will use the original default sketch for a test. Should have thought of it myself
Thanks. Will keep you posted ...

OK, so here is the result:

Code: Select all

send: 27-27-255-255 s=255,c=3,t=7,pt=0,l=0,st=fail:
                                                   repeater started, id 27
                                                                          send: 27-27-255-0 s=255,c=0,t=18,pt=0,l=5,st=fail:1.4.1
                                                 send: 27-27-255-0 s=255,c=3,t=6,pt=1,l=1,st=fail:255
                     send: 27-27-255-0 s=255,c=3,t=11,pt=0,l=14,st=fail:Relay & Button
      send: 27-27-255-0 s=255,c=3,t=12,pt=0,l=3,st=fail:1.0
                                                           send: 27-27-255-0 s=1,c=0,t=3,pt=0,l=5,st=fail:1.4.1

I cannot really interpret what these numbers mean. st=fail suggests, that something is wrong, but on Domoticz everything looks fine.
Excerpts from the Domoticz log:

Code: Select all

2015-04-25 10:38:58.113 MySensors: Node: 27, Sketch Name: Relay & Button
2015-04-25 10:38:58.162 MySensors: Node: 27, Sketch Version: 1.0
2015-04-25 10:38:58.204 (Uno SerialGW) Lighting 2 (Unknown)

The device shows in Domoticz (as light) and I can switch it on and off in Domoticz, but in the output of the node nothing happens.
Strange ...
Cheers

[ThinkPad]

Something is wrong with your hardware, look at the output you are getting.... Notice the:

Code: Select all

st=fail

That means it could not send or receive the command. Probably has to do with the powersupply to the nRF24L01+
Try using an external 3.3V power source for the nRF.

[joshmosh]

Hi ThinkPad,
you've made my day ! I thought that putting big fat (220 uF) capacitors across the supply pins of the nRF's would be sufficient, but I was totally wrong.
Now with a separate 3.3 V supply in addition to the capacitors did the show.

Thanks a bunch - I owe you.

Have a wonderful weekend - as I have now wit another roadblock removed.
Thank you
Cheers
Josh

How are you guys connecting the external power source for the radio?

I'm just using plain Apple USB chargers right now. Still not showing up.

Do I really need two outlets/chargers to run one sensor? Doesn't seem right to me

I am using the Apple iPad charger which effectively runs:
a Raspberry Pi 2, a external 2,5 inch harddisk and a Mysensors Gateway with the NRF24L01+/PA/LNA Antenne version which needs extra power to work.

Cool!
I think I have an old Macbook charger.

So how did you do the wiring?

[Mediacj]

I have connected the main power to one of the four front USB ports, from one front USB port I connect the micro usb cable to the micro USB port to power up.

The gateway and external harddisk are also connected to the four front USB ports.

But the NRF24L01+ is 3.3v. How do you power it?

[lrybak]

Please refer mysensors website. They nicely described how to power radio

I use a Arduino Nano as Gateway it has a 3.3V output but that is not powerful enough for the NRF24L01+ with the external Antenne version. For the standard version it works fine.

But as I use the external Antenne version you have to use a power source with enough amperage. My solution is to use the 5V output from the Nano and connect it to a power regulator (I used this one: http://www.aliexpress.com/item/3-3V-5V- ... 28385.html) and from the power regulator to the radio. And it works!

Do I need to modify the ethernet gateway code that's on MySensors.org for it to be able to work with Domoticz? I've created a ethernet gateway using an Arduino Mega2560 with an Ethernetshield and incoming messages aren't coming through correctly. I've attached some sensors and a relay. They show up correctly in Domoticz but when I click the switch to switch the relay nothing happens with the relay.

I've added some Serial.println() in the Arduino code to see what's being received by the Arduino and that doens't seem to be correct. This is what's written to the serial monitor:

Code: Select all

00;0;3;0;14;Gateway startup complete.
Incoming message
§Ñ©

Actually there is more in that message but the forum doesn't accept that. Those missing characters are blank squares.
It looks like the character encoding is off somehow. Also the part of the code that is outputting that message is the part that throws away the input because it's too long.

i have the same problem, it shows in the log, bot not in my devices,
Did you (or anyone) found a solution for this?

[gizmocuz]

you have to present your sensors, like with s_dimmer or with s_light

[joshimosh]

Good morning,
on the webpage of MySensors http://www.mysensors.org/ there is an announcement that MySensors Version 1.5 has been released (on 30 July 2015). Has any brave soul already tested the compatibilty with the gateway to Domoticz ? A number of new features have been introduced, in particular new types of sensors, new variables and OTA updates (which is of particular interest if you have - like me - a number of fairly remote nodes).

My guess is that the new sensor types and new variables cannot (yet) be used, since they have to be integrated in the gateway as well.
Perhaps the developer can comment on this ?

Thank you and all the best
Josh

Addition: I should have read the announcement at MySensors more carefully
It says there that

This version should be backward compatible with 1.4 both over-the-air and sketch-vise unless you use the constructor arguments which has changed to cope with a more flexible architecture.

But anyway ...

[ThinkPad]

For the OTA you need a custom bootloader i read somewhere.

[joshimosh]

Yes, I know. AFAIK there is a dual boot loader included in the new package, that will allow both standard and OTA loading.

Is the IR sensor supported by Domoticz?

If so, are the IR commands visable in the Log?
